I keep getting calls from this number at an increased frequency. Initially once daily at around 6:30PM and now it is every 3 hours all day long until 9PM. Nobody ever answers. Cannot understand what pleasure these people derive from annoying people?

This number keeps calling. I don't answer numbers that I do not know. From my research, it seems to be some sort of Verizon number. Does anyone know the true information on this? Has anyone answered and talked with the caller?
